CVE-2020-14954
https://notcve.org/view.php?id=CVE-2020-14954
Mutt before 1.14.4 and NeoMutt before 2020-06-19 have a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a man-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection." Mutt versiones anteriores a 1.14.4 y NeoMutt antes del 19-06-2020, presentan un problema de almacenamiento de STARTTLS que afecta a IMAP, SMTP y POP3. Cuando un servidor envía una respuesta "begin TLS", el cliente lee datos adicionales (por ejemplo, a partir de un atacante man-in-the-middle) y los evalúa en un contexto TLS, también se conoce como "response injection" • http://lists.mutt.org/pipermail/mutt-announce/Week-of-Mon-20200615/000023.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00070.html http://www.mutt.org https://github.com/neomutt/neomutt/commit/fb013ec666759cb8a9e294347c7b4c1f597639cc https://github.com/neomutt/neomutt/releases/tag/20200619 https://gitlab.com/muttmua/mutt/-/commit/c547433cdf2e79191b15c6932c57f1472bfb5ff4 https://gitlab.com/muttmua/mutt/-/issues& • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVE-2020-8184 – rubygem-rack: percent-encoded cookies can be used to overwrite existing prefixed cookie names
https://notcve.org/view.php?id=CVE-2020-8184
A reliance on cookies without validation/integrity check security vulnerability exists in rack < 2.2.3, rack < 2.1.4 that makes it is possible for an attacker to forge a secure or host-only cookie prefix. Se presenta una dependencia de las cookies sin vulnerabilidad de seguridad de control de validación e integridad en rack versiones anteriores a 2.2.3, rack versiones anteriores a 2.1.4, que hace posible a un atacante forjar un prefijo de cookie seguro o solo de host A flaw was found in rubygem-rack. An attacker may be able to trick a vulnerable application into processing an insecure (non-SSL) or cross-origin request if they can gain the ability to write arbitrary cookies that are sent to the application. The highest threat from this vulnerability is to data integrity. • https://groups.google.com/g/rubyonrails-security/c/OWtmozPH9Ak https://hackerone.com/reports/895727 https://lists.debian.org/debian-lts-announce/2020/07/msg00006.html https://lists.debian.org/debian-lts-announce/2023/01/msg00038.html https://usn.ubuntu.com/4561-1 https://access.redhat.com/security/cve/CVE-2020-8184 https://bugzilla.redhat.com/show_bug.cgi?id=1849141 • CWE-20: Improper Input Validation CWE-784: Reliance on Cookies without Validation and Integrity Checking in a Security Decision CWE-807: Reliance on Untrusted Inputs in a Security Decision •
CVE-2020-3350 – Cisco AMP for Endpoints and ClamAV Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3350
A vulnerability in the endpoint software of Cisco AMP for Endpoints and Clam AntiVirus could allow an authenticated, local attacker to cause the running software to delete arbitrary files on the system. The vulnerability is due to a race condition that could occur when scanning malicious files. An attacker with local shell access could exploit this vulnerability by executing a script that could trigger the race condition. A successful exploit could allow the attacker to delete arbitrary files on the system that the attacker would not normally have privileges to delete, producing system instability or causing the endpoint software to stop working. Una vulnerabilidad en el software de endpoint de Cisco AMP para Endpoints y Clam AntiVirus, podría permitir a un atacante local autenticado causar que el software en ejecución elimine archivos arbitrarios en el sistema. • https://lists.debian.org/debian-lts-announce/2020/08/msg00010.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IJ67VH37NCG25PICGWFWZHSVG7PBT7MC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QM7EXJHDEZJLWM2NKH6TCDXOBP5NNYIN https://security.gentoo.org/glsa/202007-23 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-famp-ZEpdXy https://usn.ubuntu.com/4435-1 https://usn.ubuntu.com/4435-2 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2020-8619 – A buffer boundary check assertion in rdataset.c can fail incorrectly during zone transfer
https://notcve.org/view.php?id=CVE-2020-8619
In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable. En las versiones ISC BIND9 BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: A menos que un servidor de nombres proporcione un servicio autorizado para una o más zonas y al menos una zona contenga una entrada sin terminal vacía que contenga un carácter asterisco ("*"), este defecto no puede ser encontrado. Un posible atacante al que se le permite cambiar el contenido de la zona, podría introducir teóricamente dicho registro para explotar esta condición y causar una denegación de servicio, aunque consideramos que el uso de este vector es poco probable porque cualquier ataque requeriría de un nivel de privilegio significativo y que sea fácilmente rastreable A flaw was found in bind when an asterisk character is present in an empty non-terminal location within the DNS graph. This flaw could trigger an assertion failure, causing bind to crash. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html https://kb.isc.org/docs/cve-2020-8619 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CNFTTYJ5JJJJ6QG3AHXJGDIIEYMDFWFW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EIOXMJX4N3LBKC65OXNBE52W4GAS7QEX https://security.netapp.com/advisory/ntap-20200625-0003 https://usn.ubuntu.com/4399-1 • CWE-404: Improper Resource Shutdown or Release CWE-617: Reachable Assertion •
CVE-2020-8618 – A buffer boundary check assertion in rdataset.c can fail incorrectly during zone transfer
https://notcve.org/view.php?id=CVE-2020-8618
An attacker who is permitted to send zone data to a server via zone transfer can exploit this to intentionally trigger the assertion failure with a specially constructed zone, denying service to clients. Un atacante al que se le permite enviar datos de zona a un servidor mediante la transferencia de zona puede explotar esto para provocar intencionalmente el fallo de aserción con una zona especialmente construida, negando el servicio a los clientes • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html https://kb.isc.org/docs/cve-2020-8618 https://security.netapp.com/advisory/ntap-20200625-0003 https://usn.ubuntu.com/4399-1 • CWE-617: Reachable Assertion •
